Meaning and history
Latinized form of Greek Κυνθία (Kynthia), meaning “woman from Cynthus,” an epithet of the Greek moon goddess Artemis because Cynthus was the mountain on Delos where she and her twin brother Apollo were born. The name was not used as a given name until the Renaissance and did not become common in the English-speaking world until the 19th century. It peaked in popularity in the United States in 1957 and has declined steadily since then.
